Well, it is trivially easy to have a user+ domain that exceeds 40
characters. In fact, with a 31 character limit on the OS filename it
only takes a 5 character domain to break 40 characters (@12345.tld = 41
characters)

I know worldnet had some trouble with this when they started up. Since
you had to authenticate as "[EMAIL PROTECTED]" they had the
mail servers blow up if someone with a 20 character user name checked
mail. Rather than hack pop3 they limited user names to 15 characters,
iirc. Details are fuzzy, I worked tech-support for AT&T for a pbrief
period when they were starting up Worldnet. Until recently I had some
material from them targeting 10 million users by 2000 and 20 million by
2005.
They thought they were going to kill AOL.

The way to deal with it would be for SIMS to see the requested hostname
of the connection. So if I have two domains, IloveAlysonHannigan.com
and IhateBrateneySpear.com when I connect to
"mail.IhateBrateneySpear.com" as user "fred" SIMS sees the domain and
looks at the right space. I don't know if that's reasonable. Or heck,
possible.
On the other hand, it is exceedingly minor and I wouldn't suggest
anyone waste more than a few minutes on it, if that.
